Map of select IRC data for the Florida Keys
Florida Keys History and Distribution: First collected between 1838 and 1853 by John Loomis Blodgett on Big Pine Key. Reported in
1913 by John Kunkel Small for hammocks from the upper Keys to the lower Keys, but his definition of upper Keys included the middle Keys south and west to West Summerland Key in the lower Keys. Collected in the lower sandy Keys by John H. Davis in 1940 (s.n., FLAS). We consider this native from the middle Keys to the lower sandy Keys.
